In the illustrated example of our improved burner a pan 15 is provided rigidly sustained in lhorizontal position by legs 16 which are in two sections, the opposed threaded ends 1T, 18 of which engage in threaded holes inthe pan 15. The upper ends of the legs have shoulders 19 Von which vthe burner shell 20 rests at the top of the burner, said shell having a suitable cover 21. The pan has an annular series of holes 22 which receives approximately U-shaped wires 23 on which rests an asbestos ring 24.

The pan 15 and its asbestos ring 24 are in the plane approximately of the plane of the -ting being suitably fastened to the pan 15 as by a set screw 29 in an arm 15a on said pan. Beneath the fan'25 is an upper plate 30 having an annular 'series of 'air passages and al lower plate 31 having an annular series of air passages adapted to bebrought into register to a greater or less extent with the openings of the plate 30. In forming the openings in the lower plate 31 said plate is formed with deflecting members 31 at each opening for ...directing air approximately tangentially. The plate 31 is at the end of a ilaring'fitting 32 secured to a sleeve 33 concentric with Athe spindle 26, the lowervend of said sleeve'being threaded into tha arm 15. Thelower plate 31 is rigid with an outer tube 34 surrounding the sleeve 33 and sustained by a spring 35 coiled about said sleeve and festin on the fuel supply fitting 28. Thus, whi e oilrises upwardly through the sleeve 33 from the fitting 28 air rises through the pea l5 and passes up;

I wardly through the same and the plate 30 to theoutside of the tube 34 to the plate 31 the Haine.

'has a pointer -mostatic assemblage and a cylinder 59 contightly on Av pilot light is provided by a gas pipe 37 having a tip or nozzle 38 in a nipple 39 secured to a shell 40 rising from the pan 15.

The plate 31 is regulated automatically from a thermostat as follows: The tube 34 carrying said regulating plate 31 has a fiange collar at its lower end above the spring 35. Rigid with saideollar is an arm 42 having an upturned hook 43 at its lower end engaged by an eye 44 on an operating rod 45. The rod 45 connects at its opposite end with one arm of a. bellcrank lever 46 secured to any suitable fixed support and A- here'shown as fulcrumed on a clamp band 47'pertaining to the fuel reservoir as hereinafter explained.

The. other arm of vsaid bellcrank lever 46 has a weight thereon and secured tothe arm is a wire or cable 49`connected witlr the thermostat and incidentally connected with the fuel regulator as hereinafter explained. Said wire 49 runs over a sheave 5 0 on topof a thermostat designated generally 'by the numeral .51 and comprising a suitably secured back plate attachable to any convenient wall 'or other suitable support in a room, the temperature of which is to be regulated. lVire 49 connects with a lever 52 of generallyA bellcrank form fulcrumed on the back plate of the thermostat. Said lever pin 53 disposed vertically and head 54 has a scale of temperan indicating and is secured to a atures on its periphery shank 55 threaded into the lever 52 and subject to a coil spring 56 so that by adjusting the screw 55 the spring will be more or less stressed and thereby will oppose to a greater or lesser extent the rocking -of the lever 52 according' to the temperature desired. The thermostat includes a mercury cup 57 held rigid on bracket 58 of the thertaining alcohol and adapted to move vertically in the cup 57 on a uide pin 60 extend ing upwardly from the ottom of said cup'. In the bottom of the alcohol cylinder 59 is a ball beari 60 which, however, does not tit e uide pin 60 but only sufficient movement so that the meransion of the ith the expanto give guide cury will be subject to the ex alcohol to the cylinder 59.

" sion 0f the mercury in the cup 57 and the alcohol in the cylinder 59 according to the temperature of the room the cylinder '59 will rise and will rock-the lever 52, thereby permitting the weight 4 8 acting through the..

`rod 45, the arm 42 ing registeringopenings 30' and decrease the and the tube 34 to turn the air regulating plate 31 relatively to the plate 30 for cutting down the air supply..

In order that the air supply may be manually regulated we attach to the bellcrank lever 46 al second pull wire runs over a sheave 63 on the thermostat- 5l,.the end having suitable means to hold it inposition'` there being shown a ring 64 thereon adapted to be engaged with a. fastening screw 65 or the like.

A fuel reservoir 67 is provided having au' inletpipe 68 in the bottom thereof and an outletpipe 69 leading from the bottom to the fitting 28. From the inlet`pipe 68 the fuel passes to the reservoir 67 through a strainer 70. en'd of the inlet pipe 68 the same is fitted with a partiti-on 71 having a central fuel opening controlled' by a disk valve 72,011 the lower end of a spindle 73 advantageously.

In advance of the discharge or 4cable 62 which the back plate 'of of said wire 62 las the strainer the top of the inlet wipe 68" v is fittedwith upper and lower disks a havspindle 7 3 freely passes and a. self-centering ring 77 is disposed between said upper. and,v

the spinti lower plates and snugly receivesv 73. A float 78 in the reservoir 67 is rigidl with a sleeve 79 extending about the spindle through which .the

7 3 through the top 74 of the reservoir and l..

on top of said sleeve 79 rests a' lever 80 forked to pass at opposite sides of the spindle 73 and fulcrumed above as on a` clamp The forked endiif, I

bracket 81 on said stem.

the lever has a slot and pin connebrillm"y with a slide 82 on a vertical tube 83 thro/raging which the wire 49 passes, said tube being/ rigid with a bracket 84 on the reservoir 67 A stop screw 85 limits the downward movement ofthe slide 82 by contacting with the top 74 and a' set collar` 83'l on the tube 83 above the slide 82 limits the upward movement of said slide. Connect-ion between the slide 82 and the wire 49 is established by a cross pin 86, the tube ted as at 87 to. allow movements of the slide.

With the rising of the fuel in the reservoir 67 the iioat 78 will raise lever 80, bracket 81 and stem 73, thereby closing valve 72.

An upward movement of the lever 46 b v a pull on the wire 49 or 62 will through said lever 46 exert a pull on the operating rod 45 which will give a turning movement to arm 42and tube 44, thereby regulating valve lplate 31 relatively flow of air. b The fuel and air will be thoroughlyV mixed the ing to plate under side of the fanblades, said fan becaused to-r'evolve b 83 being vertically slotthe .draft through turning the air the fan 25 as the fuel and air emerge at t 9i pivoted at one end on screw 93 secured to stand 90 by clamp 93a. Arm 94 is normally Sustained in the raised position by a spring 95, so that the dog'92 is in engagement with one of the teeth 9F. On the outer end of the arm 94 is a bucket 96 adapted to receive drip from a drip pipe 97 leading from *a drip pan 98 disposed below the main pan l5 and here shown as sustained on the lower end of the fitting 28. A drip pipe 99 leads from the main pan 15 to the auxiliary drip pan 98.

Upon an excess of fuel beingfed to the burner, the fuel will fall to the lpan l5 and flow from the same through pipe 99 to the drip pan 98, thence by pipe 97 to the bucket 96 and when a predetermined quantityhas been received by said bucket the tension of the spring 95, will be overcome, the arm 94 will be drawndownivardly, thereby releasing the dog 92 from the weighted arm 91 thus permitting said weighted arm to yturn the valve 89 toward the closed position to the,extent'of one tooth and this operation will be repeated if the fuel continues to accumulate 1n thebucket 96. l

The gas pipe 37, fuel pipe 69, drip pipe 97, and pull'rod/L, are in-pra'ctice passed through the. ash pit vdoor of the furnace, the stand 91 w1th\the reservoir 67 being posi tioned in front of the furnace and the therpositioned in the room above" mostat being to be regulate Ve would state in conclusion that While the illustrated example constitutes a practii cal embodiment of our invention, We do not limit ourselves strictly to the exact details herein illustrated, since, manifestly, the

-Same can be considerably varied Without departure from the spirit of the invention as defined in the appended claims. v

Having thus described our invention', We claim:

1. In a burner of, the class described, a fuel reservoir, an inlet pipe leading int-o the bottom of said reservoir, a valve controllingr the discharge of fuel from said inlet, pipe, a vertical spindle carrying said valve and extending above said reservoir, a oat in said reservoir, a fuel delivery means, and means connected with said spindle and operative l,by said Hoat to move the spindle for opening or closing said valve; together with means to conduct air to the discharge of said fuel delivery means, means to'regulate the discharge of the air, and means to operate said air regulating means simultaneously with the movements of said spindle.
